WILLIAM B. KING, OF NEEDHAIM, MASSACHUSETTS, ASSIGNOR TO UNITED SHOEWIACHINERY CORPORATION, OF PATERSON, NEW JERSEY, A CORPORATION OF NEWERSEY.

Application filed June 13,

T 0 all whom it may concern:

Be it known that I, WILLIAM B. limo, a citizen of the United States,residing at Needham, in the county of Norfolk and State ofMassachusetts, have invented certain improvements in Presses, of whichthe following description, in connection with the accompanying drawings,is a specification, like reference characters on the drawings indicatinglike parts in the several ngures.

This invention relates to improvements in presses of that type in whicha pressure applying member is movable into various positions relative toa. bed to apply pressure to difierent parts of stock located between thepressure member and the bed. while presses of this type may be used formany different purposes, they are often used for dieing-out sheetmaterial, and accordingly I have shown my invention applied to a pressof this kind, it being understood that it is by no means limited to usewith machines for accomplishing this result.

An important feature of this invention relates to the provision in apress of the character described of improved power means for moving thepresser member laterally over the work supporting bed, the constructionproviding preferably a manually controllable member mounted on thepresser member and operable to control the said power means.

Practically all types of presses are provided withpower means forcausing pressure applying movements of the movable presser member,manually operable means being employed for controlling the power means.It is an object of the present invention to provide a single manuallyoperable means for controlling both the power means for causing lateralmovement of the fpresser member over the work supporting bed and thepower means for eifecting the pressure applying operations of thepresser men her, the said manually operable means beingpreferablymounted on the presser member for movement therewith, thusproviding a controlling means easily accessible to the operator andreadily operable to eil'ect'the movements of the presser member inproper sequence.

Another important feature of the invention relates to improvements in atype of press which comprises a work supporting rnnss.

1: simple, compact and most efficient power means for rotating thepresser member about the axis of the post comprising a de vice mountedfor rotation on the post and providing a movingsurface to which thepresser member maybe operatively connected at the will of the operatorto swing the presser member over the work supporting bed. Preferably twosuch devices are mounted on the post for rotation in oppositedirections, means being provided for Se lectively connecting the pressermember thereto whereby the latter may be moved in the desired directionover the work on the support.

Another feature of importance relates to an improved starting mechanismfor controlling the power means for effecting the pressure applyingoperations of the presser member.

Preferably this mechanism comprises a lever mounted on the frame ofthemachine and having an arcual portion which provides contactingsurface for a single roll carried by another lever mounted on thepresser member, the construction and arrangement being such that theroll remains in contact with the arcual surface in all positions of thepresser member and without any tendency to a binding action duringmovements of the latter. 7

A principal feature of the starting mechanism resides in the provisionof a handle for the mechanism mounted on the presser member and soarranged as to remain substantially stationary in space during; thereciprocation of the presser member in a pressure applying operation,whereby the pulleys on the supporting post of the presser member;

Fig. 3 is a detail of the starting mechanism; and j Fig. 4: is a sectionof the presser member in front or the operating pulleys and showing theattachments ot the pulley bands to the presser member.

In the illustrative embodiment of the invention there are shown a worksupporting bed 6 and a presser member 8 movable laterally over the worksupporting bed into different operative positions with respect to thework on the bed. Mounted in bearings 10' and 12 of the frame 14: of themachine is a post 16 which supports the presser member 8 for rotationabout the axis or the post.

Preferably, and as shown, the presser mem her 8 is fixedly secured tothe post 16, and upon reciprocation of the latter vertically the pressermember is caused to approach and recede from the work supporting bed inpressure applying operations upon work on the bed. Mounted in the frameor the machine is a shaft 18 operatively connected to the post 16 bymeans not shown but which may be according to the construct-iondisclosed in the patent to Arthur Bates, No. 921,503, granted May 11,1909, said shaft carrying a power pulley 20, clutching mechanism beingprovided for connecting the shaft to the power pulley at the will of theoperator, the said clutching means being preferably housed in a casing22 and being of a well-known type of one-revolution clutch mechanismpreferably, though not necessarily, like that shown in said patent.Startin means under the control of the op erator tor causing operationof the machine as desired comprises a lever pivoted on the frame of themachine and connected by a link to the clutch mechanism so that uponoperation of the lever the clutch may be tripped and thuscause operativeconnection of the shaft and power pulley.

An improved form of starting means comprises a lever 2a pivoted at 28 tothe upper part of the frame of the machine and having at its forward endan arcual portion 30 extending in front or the upper bearing 12. By thisarrangement of the tripping lever the bearing 32 ot the presser member 8may be made as deep as desired, since no part of the lever is interposedbetween the presser member and the bearing 12, the construction andarrangement differing in this respect from that shown in said patent toBates. In other words, the bearing may be extended along the post 16practically into contact with the lower surface of the frame bearing 12when it is desired to make the presser member 8 especially heavy andgive it a deep bearing on the post. In co-operation with the lever 24there is provided a lever-clevice mounted on the presser member, theconstruction being such that the device on the presser member engagesthe upper surface only of the arcual portion 30 of the lever 2a,-

thus providing against any tendency of a binding action between theengaging portions as the presser member movesabout its axis oi":support. Preferably, the lever device on the presser member comprisestwo levers 3e and 36 mounted on pivot supports 38 and i0 respectively,the supports being vertically adjustable as indicated by set screws asprovided for securing the supports in adjusted position. lhe arms a, aof the lever 3e are equal in length in the horizontal direction as alsoare the arms 6, b of the lever 36, it being immaterial whether or notthe arm a is equal in length to the arm b. As shown, the arm Z) of lever36 carries a roll it for engaging the upper surt'ace of the arcualportion 30 of the lever 2a. At the other end of the lever device, thearm a of the lever 54 carries a handle member l6 having shoulders orcollar portions 48 for engaging the upper and lower surfaces of the endof the lever arm a. In order that the handle as may move laterally withrespect to the lever 3d, the said lever is provided with a slotextending transversely ot' the end or the lever, the arrangement of thehandle and elongated slot having a purpose which will be later pointedout in connection with means for moving the presser member laterally:t'rom and into position over the work supporting bed. i I

An intermeshing gear tooth connection is provided at 0 between theadjacent ends of the levers 34: and 36, and upon depression of thehandle as, the lever device just described will operate through the rollat to depress the arcual portion 30 or the lever 2e and thus trip theclutch on the main shaft of the machine. After the clutch is tripped thepresser member moves downwardly in a pressure applying operationcarrying with it the pivots 38 and of the levers 3 s and 36. As the rolle4. cannot move downwardly with the presser member 8, the lever 36swings about its pivot -10 causing the adjacent connected arms a and bof the levers 34; and 36 to move downwardly and the other arm a of leverto move upwardly oarrying the handle 4-6 upwardlyaway from the pressermember .8 a distance equal to the amount that the presser member isdepressed in its pressure applying movement.

In other words, the downward movement 7 operator, it being clear thatthe handle remains practically stationary in space during a completereciprocation or the presser member. Another important advantage of thestarting means resides in the construction by which no binding actiontakes place between any of its parts during movement of the pressermember laterally over the work support or upon reciprocatory movementtoward and from the work support.

In most of the presses as at pr" eat constructed, the presser member ismoved laterally over the work supporting bed by force exerted directlyby the operator. l /hen the presser member is particularly heavy and inother constructions also, it is desirable to provide power means formoving the presser member laterally over the bed thus lesseningmaterially the labor involved in operating' a press of this kind. In theillustrated machine the power means for moving the presser membercomprises connections with the power pulley on the main shaft oi themachine so constructed and arranged as to impart lateral movement to thepresser member at he will or" the operator. In the construction shown,the pulley 20 is provided with a pulley 50 formed integrally therewithor securely attached thereto and about Which passes an endless cable 5There are provided also pulleys and 56 mounted preferably on the post 16and arranged to be driven constantly in opposite directions by means oithe cable 52. The upper run 58 or the cable 52 passes over an idler 60and thence around the upper pulley 54 in a groove therein and from thereto an idler pulley 6:2 mounted on the frame of the machine. The cablepasses around this idler 62 and thence as the lower run 6d of the cableit passes around the lower pulley 56 in a groove therein and thence toand over an idler 66 to extend to and become continuous with the cablepassingaround tl e pulley 50. In the construction shown, the idlers G0and 66 are mounted upon a bracket 68 extending from the frame of themachine. the pulley 62 being mounted prelierably in a slidable bearing(not shown) on the frame 14 so that it may be adjusted to take up anyslack in the cable 52. Upon tracing the course of the endless cable 52it will. be seen that the upper pulley 5% turns in the oppositedirection to the lower pulley 56. thus providing surfaces In ving inopposite directions to which the presser member may be operativelyconnected when it is desired to move the presser member into and out ofposition over the work support-- ing bed. In the illustrativeconstruction, the connections between the presser member and the pulleys54; and 56 comprise a lever 70 pivotally mounted at 72 upon a. web 74in. the presser member 8. the free end of the lever receiving forvertical sliding moveit will be seen that when the lcv.

It will he observed thatthe handle 46 is moved in the directioi'i that it desired to more thepresser member and that by this movement or": the lever the properpulley is connected to mov the presser member in the direction the handmoves in actuating the lever 70. New. it will be seen that the elongate.slot in the outer end of the lever 3 is for the purpose of permittinglateral movement of the lever 70, to which the handle 46 connected.while retaining: operative connection li ctween the handle 46 and thelever E l: so that at the end of the lateral movement of the lever 70,said handle may be depressed to operate the lever 34: and thus cause atri ping of the clutch on the main shaft of machine, by which a pressureapplying opration is *oduced.

ln the operation of the machine, work is placed upon the work.supporting bed 6 and the presser member is moved to one side to permitlight to reach the work and to provide space for the manipulation oi thework and or the die in locating the latter in de sired relation to thework. When the work is properly arranged, the presser member is swung tooperative position, the operator grasping the handle as and moving it inthe direction that he desires the presser member to move whe eupou thepower means is connected to the presser member to assist the operator inmoving the prcsser member, the construction and arrangement being suchthat the presscr member follows the hand of the operator with the veryminimum of etfort on his part. As the presser member is approaching thedie and without waiting until it is directly over the die, the machineis tripped by depressing the handle it; whereupon a pressure applyingoperation takes place, thus forcing the die through the work. Themachine provided with a brake mechanism indicated 90 and di closed inthe patent to Eaton No. l,00 l,757, granted October 3, 1911, which makesit possible to trip the clutch while the presser member is still movinglaterally, as described, the brake operating to stop the lateralmovement just as the presser member is about to strike the die, thuspreventing the striking of a glancing blow. It should be pointed outthat as the handle 46 is depressed its movement laterally is terminated,while the presser member continues to move under its acquired momentumwith the result that it almost instantly disconnects itself from thepulley which was moving it. Jitter the pressure applying operation, thepresser member is swung away from over the die by pressing laterally onthe handle 46 in whichever direction it is desired that the pressermember shall move, whereupon the proper pulley is connected to move thepresser member. If desired the presser member may be moved very rapidlyaway from over the die by pressing firmly in a lateral direction on thehandle L6, in which case it becomes necessary to check the'lateralmovement of the presser member when it has reached the position selectedby moving the handle 46 in the opposite direction, whereupon the otherpulley is at once applied to the presser member as a brake device tobring it to rest.
